The following courses have been added or changed as a result of the November 2006 new graduate degree requirements and are now part of the department's Graduate Regulations.

CS 503. Foundations of Computer Science  (Modified Description)
This is the study of mathematical foundations of computing. Topics include finite automata and regular languages, pushdown automata and context-free languages, Turing machines and decidability, and an introduction to computational complexity. Prerequisites: Knowledge of discrete mathematics and algorithms at the undergraduate level, and some facility with reading and writing mathematical proofs.

CS 5003. Foundations of Computer Science: an Introduction  (New Course)
This is the study of mathematical foundations of computing, at a slower pace than that of CS 503 and with correspondingly fewer background assumptions. Topics include finite automata and regular languages, pushdown automata and context-free languages, Turing machines and decidability, and an introduction to computational complexity. Prerequisite: an undergraduate course in discrete mathematics.

CS 584. Algorithms: Design and Analysis  (New Course)
This covers the same material as CS5084 though at a more advanced level. As background, students should have experience writing programs in a recursive, high-level language and should have the background in mathematics that could be expected from a BS in Computer Science.

CS 5084. Introduction to Algorithms: Design and Analysis  (Modified Description)
This course is an introduction to the design, analysis and proofs of correctness of algorithms. Examples are drawn from algorithms for many areas. Analysis techniques include asymptotic worst case and average case, as well as amortized analysis. Average case analysis includes the development of a probability model. Techniques for proving lower bounds on complexity are discussed, along with NP-completeness. Prerequisites: an undergraduate knowledge of discrete mathematics and data structures. Note: students with a strong background in design and analysis of computer systems, at the level equal to a BS in computer science, should not take CS 5084 and should consider taking CS 504 or CS 584.
